Abrégé
(EN)
Retroreflective articles of the invention comprise a continuous base layer (16) and a multi-color polymeric top layer. The invention also includes methods of making such retroreflective articles. The retroreflective articles of the invention provide excellent daytime contrast while maintaining nighttime retroreflectivity. Variously colored segments of polymer are directly and either sequentially or simultaneously coated onto a continuous backing to form a multi-colored top layer. Durability over existing multi-colored retroreflective articles is enhanced by use of a continuous base layer.
(FR)
Les articles rétroréfléchissants faisant l'objet de cette invention comprennent une couche de base continue (16) et une couche supérieure polymère multicolore. Cette invention porte également sur des procédés de fabrication de ces articles rétroréfléchissants. Ces articles rétroréfléchissants se caractérisent par un excellent contraste de jour, tout en conservant leur pouvoir rétroréfléchissant de nuit. Des segments polymères de diverses couleurs sont directement et soit séquentiellement soit simultanément déposés sur une couche dorsale continue, de façon à former une couche supérieure multicolore. On améliore la durabilité de ces articles par rapport aux articles rétroréfléchissants multicolores existants, grâce à l'utilisation d'une couche de base continue.
